co2 industries fermentation, petrochemical, power, cement, natural gas, iron and steel industry.
co2 reduces calorific values and causes corrosion
co2 capture in hydrogen: ourification
ammonia: co2 poisons the catalyst

avoiding co2 emissions (imooosible)
find co2% for gas streams of vrious processes
limitations: expensive; temprorary; doesnot add value; dangerous leaks may lead to aphyxation (1986 incident)
